Unscrew the infotainment unit from its mount using the Torx screwdriver.
Inspect all wiring connections for any signs of damage, corrosion, or looseness.
Reconnect any loose wires and replace damaged connectors as needed.

6. Test with Different USB Device

Connect a different USB device to the infotainment system.
Check if the system remains responsive while playing audio or accessing files from the new device.
If the system functions properly, the previous USB device may be faulty.
